Improvement in earth-scrapers



UNITED STATESv PATENT @einen NELSON PECK, OF JAY, NEW YORK.

IMPROVEMENT lN EARTH-SCHAPEHS.

Specification forming part of Letters Patent No. SVJN, dated December16, 1502.

To all whom, it may concern.:

Be it known that I, NnLsoN PEGK, of Jay, in the county of Essex andState of New York, have invented a new and Improved Earth- Scraper; andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdra-wings, making a part of this specification, in which- Figure l is aside sectional view of my invention, taken in the line .fr Fig. 2. Fig.2 is a back view of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to a new and improved earth-scraper, designed forrepairing roads and for general grading purposes.

The invention consists in a novel and improved combination andarrangement of the scraper, wheels, draft-pole, and levers, ashereinafter fully shown and described, whereby the scraper may, with thegreatest facility, be raised and lowered--lowered to perform its workand raised to discharge its load.

The invention is an improvement on a device for the same purposepatented by me January 3, 1860. The principal advantage of the formerconsists in relieving the wheels of all lateral strain or pressure inelevating the loaded scrapena result which attended the operation of thepatented machine.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it with reference to the drawings.

A represents the axle of the machine, the ends t c of which are bent atright angles to its main portion, and are provided with arms b b, onwhich the wheels' B B are tted to rotate freely.

G is the scraper, which may be constructed of wood shod with metal atits lower end to resist wear. This scraper extends the whole width ofthe space between the bent ends a c of the axle A, and it is of concaveform at its face or front side, its lower end being' about in line withthe centers ofthe wheels or the arms b b thereof. To the upper part ofthe scraper, at its center, the draftpole D is rigidly attached, and thedraft-pole is connected to the ends (t c of the axle by means of obliquerods c c.

To the back of the scraper C there are attached two levers, E E, theirfulcrum-pins d passing through their centers. The lower ends of theselevers are connected by links or arms c c to the bent ends c c of theaxle A, the lower ends of the links or arms c c being fitted in eyes j"at the under sides of a a. The inner ends of the leversE E are connectedby rods g g to the outer end of a lever, F, which is connected at itsfront end by a fulcrum-rod, h, with an upright, fi, attached to thedraftpole D. The lever F, near its outer end, is provided with a guide,j, which works on an upright, k, attached to the upper edge of thescraper, said upright being provided at one side with a notch, l, at itsupper and lower end, and having a spring, my, at its opposite side. Thisspring turns the lever F into either of the notches l as it is raisedand lowered.

From the above description it will be seen that when the outer end ofthe lever F is depressed and fitted in the lower notch, Z, of theupright r, the scraper C will be at its lowest point, and the wheels B Bsome distance above the lower edge of the scraper, whichis in thisadjustment of the parts in its working position, and will scrape up theearth before it as the machineis drawn along. The scraper is raised inorder that it may discharge its load by raising the outer end of thelever F, the wheels B in this case resting upon the earth, and the loweredge of the scraper being above it, as shown in red outline in Fig. l.By this arrangement the wheels B are not subjected to any lateral strainwhen the scraper C is raised, as the wheels are attached to a permanentaxle, or one which is not connected with the levers E E, in such amanner as to be affected by their action, as is the case in the patentedmachine previously alluded to.

Another advantage myinvention possesses is that the aXle A, inconsequence of being bent at the ends, as shown, admits of the lowerpart of the scraper being in line with the centers of the wheels.

admits of the machine operating perfectly in case of being backed into aditch or hollow 1n a road, the scraper being brought in contact Thisarrangement' with the earth Without the necessity of forcing to operatesubstantially as and for the purpose Jche Wheels up the back benk orslope of the herein setV forth.
